You also can't put unidentical drives into RAID 0 but you don't see that stopping him...

LOL

+rep man. haha.

Indeed, if you put two unidentical drives in RAID0, you will just loose the extra capacity of the bigger one, am I mistaken here ?

i always thought it just won't work...? or does it work like ram like Eye-I-aie suggested? beats me

A long time ago it just wouldn't work unless you were using identical drives.

Now, you mostly just lose capacity (if both/all are 5400/7200 RPM drives at least).

So, you're both right.

Ideally though, you should still not mix drives as timing differences could give you a very unstable RAID setup.

yea i wouldn't mess around with that... i'd personally make sure i'd have identical drives....

thanks for clearing that up though bro

Yeah unidentical drives in any RAID format is generally not a good idea. It should work flawlessly, but if you RAID a SSD and HDD, you get the WORST of both worlds. You're limited by the HDD's read and write speed (well at about 1.5 times the speed if in RAID 0) AND you're limited by the RAID's size (times two in RAID 0).

So a 128 GB SSD + 500 GB HDD in RAID 0 is seen as a single ~256GB drive at slower speed than just the SSD.

^^^^ which equals BIG WASTE OF MONEY ... lol

Yeah, but if you happen to have a whole bunch of, say, 500GB drives with different amounts of platters and from different manufacturers, it's not a big problem.

I recall running across a page with instructions on how to update a 256GB Samsung SSD to firmware with TRIM support by connecting it to a desktop and using some tool. I can't seem to find that page anymore, anyone have a pointer handy?
